My first motorcycle build, however Ive built many cars and previously built parts for Boeing space-x and NASA. I don't care to turn my 500t into a cbr, I just like the rims, coupled with the modern forks. More aesthetics than anything (plus dual front disc brakes)

As for the rear, what's more involved? Converting to hardtail?

Yes I get it. Flame suit has been on since I joined the forum. I'm not your typical "retro" or "conventional" guy. I like very different things. I enjoy heavily modded vehicles. Unique motor swaps. Old things with a surge of new life. Taking pretty things and making them ugly. It's weird. I know I'm asking for information on something that most people here will vomit over. I have my style and interests though, I figured someone would be able to point me in the correct direction without having to design and build everything custom.

Well, you've got no chance of fitting the CBR rim inside the CB swingarm, so you need to swap in the entire CBR rear end. Which means you have to shave X amount of meat off the CBR pivot area because it's wider then the CB. Then you'll have different diameter pivot bolts (CBR will be larger diameter). So, you could probably ream out the CB swingarm pivot holes and get a new spindle made up.

Then you have to think about monoshock or CB twin shocks. Twin shock would be easier because it just means welding some twin shock mounts to the CBR swingarm, but the top mounts are going to be closer together on the CB frame than the CBR swingarm width, so the shocks need spacing out up top.

Then you have to try and line up the chain between the front sprocket and the rear because it will probably be a few inches off. You can trim a little off the cush drive, and space out a little at the front sprocket, but it wont be enough. So you'll have to look at an outrigger front sprocket or a jackshaft to run 2 chains.

Aint simple. If it was you would see hundreds of them done.

Thank you good sir. I appreciate the time spent for the response and the information within. I'm going to look further into the conversion with this info in mind and weigh my options. Again, thank you for the help!
